No. 894,716. I

- T all who m it may concern Be it known that I, DANIEL L- APPEL- KBERRY, a citizen of the United States, residing the same from being turned off the spindlesby thejaction of the wheels, the con-' struction hereinafter described permitting the spindles to be readily and quickly moved whenever necessary.- With the above general object in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed. I In the. accompanying drawings, Figure 1 is; an elevation of a sufficient portion of a spindle to show. the nut lock applied thereto. Fig. 2 is. a similar view taken at right angles to F ig, 1-. ,Fig. 3 is a sectional view ofthe same Fig. 4 is an inner face view of the nut or cap. Fig. 5 is a broken outer end view of the, cap. Fig. 6 is a detail perspective view, showing the spindle extension. Fig. 7 is a perspective view of an implement used for applying and removing thenut or cap. i

Referring to the drawings, 1 designates an ordinary vehicle axle spindle which, for the .PUIPQSGrOf carrying out the present invention,i'is provided w1th an" end extension 2 which is in the form of a flat-sided. ellipse in cross section, as shown in Figs. 5 .an d 6, the inner. endof said extension immediately adjacent to the contiguous end of thespind-le lbeing notched or cut away at posite sides, as shown at 3, to provide prdjecting shoulders 4 behind which corresponding shoulders on the cap or nut are adapted to engage to sustain the lateral pressure of the wheel hub, thereby removing all strain from the cap' or -n ut locking device hereinafter particularly described. The spindle extenof the cap or nut hereinafter described.

sion 2 further provided in its opposite fiat sides with. sockets 5 adjacent to the shoulders-4 andadapted to receive :the latches '6 designates the cap-j. or nut which re cesse'dto fit over the spindle extension 2 in the manner best illustrated in Fig. in

which it will be observed that said ca is providedat itsinner end with a circum ferential flange 7 which is adapted to receive the pressure of and form a bearing for the outer end spindle 1. nut 6. is, in the main, round so as to turn upon the extension 2 but adjacent to its inner end, the side of said bore is reduced. by providing inwardly projecting, oppositely located thoulders 9, the inner edges of of ,a' suitable thickness to fit behind the said shoulders4 and the adjacent extremit ders 9 are thus-engaged with the shoulders 4, the cap or n'ut is positively prevented loo between the cap and the spindle and ,prelivent the cap from turning on the spindle so as not to et loose. When the latches are engaged wit the sockets 5, the shoulders 9 spindle extension and it is only by a partial ders 9 may be' carried away from behind the of the spindle proper, so that when the shou from moving outward onthe spindle ex'tenk in 'he sides of the cap or nut and into the S00 ets' 5 of the extension? so as to'form a ofthe cap rest behind the'shoulders 4 of the rotation of the cap or nut, '6 that the 'shoul-,

of the hub of the wheel mounted on the 'Iheihterior'bore 8 of the cap or i which are straight, as shown in Fig. 4, and I parallel to each other, said shoulders being shoulders '4 of the extension 2 and between shoulders 4 so as to e'nable the cap to he slid ofi the extension 2. The latches 10 are ful crumed-at 12 on lugs13 extending outward from opposite sides of the cap or nut 6 and said latches are provided with outwardly extendin .le'ver portions 14 adapted to be grasped etween the fingers 'or forced to- .wardeach otherby a suitable implement to rock the latches and move the extremities thereof out of engagement with the socket 5 to release the cap and allow thelatter to be turned, The latches 10 are normally held in engagement with the sockets 5 by means of springs 1.5 interposed between the latches andthe'adjacent faces of the nut or cap 6, as clearly shown in Figs. 3 and5.

1. Toremove the cap or nut from-the spindle,

theilever extensions 14 are pressed toward Qof the latches out of engagemcnt with the each-other, thereby moving the extremities other and cause'them to maintain the" I is especially designed for use in connection an ordinary pair of pliers but ditiering there- 1 sockets 5, whereupon the cap or nut may be turned to move the shoulders 9 outward from in that the jaws 16 of the pliers are forked so as to straddle the lugs 13 and enable the crown portions 17' of the jaws to engage the lever'extensions 14 for the purpose of pressing the same toward each other 5 to swing the engagipg portions of the latches out otengagement with the spindle extension 2. The handle: portions 18 of the jaws have a spring 19 interposed between them which operates to hold the jaws toward each i latches 10 in an inoperative position during the operation of removing and a 'iplying the cap or nut.

From the foregoing description, it will be seen that all strain and pressure brought tov bear against-the cap or nut by the hub of the wheel is sustained by the interlocking shoulders 4 and 9, thus removing all strain from the latches, the latter being used merely to prevent the cap or nut from rotating under the action ot the revolving wheel hub, This removes'all liability of the cap or nut to unscrew. The cap or nut may, ol course, be made of any size to lit any vehicle, and ex tra washers of different thicknesses may be supplied to be inserted between the hub of the wheel and the flange 7, for the purpose oftaking-up wear, and such washers may be applied instantly without alteration. While thenut lock'hereinabove described I with the spindles of vehicle axles,'it will be apparent that'the same may be used in any place where it is necessary to prevent nuts irom working loose.

I claim:

1. The combination of a member having an extremity of greater transverse dimeur a bore ofgreater diameter than the greates transverse dimension of the said extremity and also having webs adapted to engage be- 1 bind the shoulders for preventing longitudinal displacement of the nut and having oppositely disposed openings adapted to reglster with the SOtiGt, L-shaped locking members pivotally mounted on the nut ach with an arm disposed in an opening ol the latter and adapted to terminally engage in the registering socket, and a separate spring interposed between each locking member and the outside ol the .nut for holding the said members in locking )osltion.

2. The combination oi transversely extending sockets and oppositely disposed shoulders, a nut adapted to be assembled over the end of the member and )rovided with webs adapted to engage beliind the shoulders, levers l'ulcrumed on the nut at opposite sides thereof and provided with rightangularly disposed extremities passing through openings in the. nut adapted to engage in the sockets, the levers being of less length than the axial llllllOlisltHt ol' the nut, a spring interposed between each lever and nut and covered by the lever to be protected thereby, and means for securing each spring to the nut and adjacent lever.

In testimony whereof, .l allix my signaturein presence of two witnesses.
